Introduction

The Latvian elevation model in 20m grid resolution is a digital terrain model produced by the Geospatial Information Agency of Latvia (Latvijas Ģeotelpiskās Informācijas Aģentūras). The model was derived from LiDAR scans and stereo-orthophotos. Spatial coverage is for the whole of Latvia. The data available in windPRO was accessed during early 2019 – and holds data with source-date 2017.

Dataset Overview

  • Spatial Coverage: Lativa
  • Resolution: 20 m
  • Data-type: Digital Terrain Model (DTM)
  • Coordinate system: Raw data was delivered as ERSI gridded files – with coordinate-system data embedded (Transverse Mercator with central median 24 degree longitude).
  • Version: Source data is from 2017.
  • Vertical Accuracy: N/A

Availability from within windPRO

The data are available directly from within windPRO in 20-meter resolution. The data can be accessed from the online-services in the following objects:

  • Line Object (with purpose to height contour lines)
  • Elevation Grid Object
